Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described and explained below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments provided by this utility model without inventive effort are within the scope of protection of this utility model.
[0025] This utility model embodiment provides a waste tire debonding and sorting device. Figure 1 This is a schematic diagram of the waste tire debonding and sorting equipment according to an embodiment of the present utility model.
[0026] refer to Figure 1 As shown, the waste tire rubber breaking and sorting equipment includes a sorting device, such as... Figure 1 , 2As shown, the sorting device includes: a first sorting component, including a cylindrical first screen 101 and a first connecting portion 102 connected to both ends of the first screen 101; a second sorting component, including a cylindrical second screen 103 and a second connecting portion 104 connected to both ends of the second screen 103; the second connecting portion 104 located at the feed end of the second sorting component is fixedly connected to the first connecting portion 102 located at the discharge end of the first sorting component; the mesh diameter of the second screen 103 is larger than the mesh diameter of the first screen 101.
[0027] Waste tire particles of different sizes entering the sorting device are conveyed to the first screen 101 via the first connecting part 102 for screening. The oversize material after screening is conveyed to the second screen 103 via the first connecting part 102 and the second connecting part 104 for screening, thus achieving the grading of waste tire particles of different sizes. Furthermore, in order to ensure that the waste tire particles are fully screened and smoothly conveyed forward in the sorting device, the sorting device is inclined downward from the feed end to the discharge end at an angle of 1.3°-1.7°.
[0028] The sorting device includes a transmission component that drives the first sorting component and the second sorting component to rotate coaxially. In some embodiments, the transmission component includes a transmission reducer 110 and a driven gear ring 111 sleeved on the first connecting portion 102. The transmission reducer 110 has a drive gear on its transmission shaft, and the drive gear meshes with the driven gear ring 111.
[0029] By using a transmission component to drive the first and second sorting components to rotate coaxially, the waste tire particles in the first and second sorting components are fully dispersed to ensure the screening effect. At the same time, it is also beneficial to the conveying of waste tire particles in the first and second sorting components, avoiding the decrease in conveying and screening efficiency caused by the accumulation of waste tire particles.
[0030] To ensure the stability of the sorting device and simultaneously enable the rotation of both the first and second sorting components, the sorting device also includes a support roller assembly 112 for supporting the sorting device. The support roller assembly 112 includes a tire sleeved around the first connecting portion 102 and the third connecting portion 106, and support rollers located on the left and right sides below the tire. For the structure of the support roller assembly 112, please refer to the structure of the support roller traveling mechanism disclosed in Chinese Patent Application No. 201911202514.4, which will not be repeated here.
[0031] The sorting device also includes a first hopper 107 located below the first screen 101, with an opening at the top, and the opening area being larger than the orthographic projection area of the first screen 101 at the top opening of the first hopper 107; and a second hopper 108 located below the second screen 103, with an opening at the top, and the opening area being larger than the orthographic projection area of the second screen 103 at the top opening of the second hopper 108. The first hopper 107 is spaced apart from the first sorting component to avoid affecting the rotation of the first sorting component, while also ensuring that the opening area of the first hopper 107 is larger than the orthographic projection area of the first screen 101 at the top opening of the first hopper 107, thus guaranteeing that all undersize material screened by the first screen 101 falls into the first hopper 107. Meanwhile, the second hopper 108 is spaced apart from the second sorting component to avoid affecting the rotation of the second sorting component. At the same time, the opening area of the second hopper 108 is limited to be larger than the orthogonal projection area of the second screen 103 at the top opening of the second hopper 108, ensuring that the undersize material screened by the second screen 103 falls into the second hopper 108.
[0032] To further ensure screening effect and grading of waste tire particles of different sizes, the sorting device also includes: a third sorting component, including a cylindrical third screen 105 and a third connecting part 106 connected to both ends of the third screen 105; the third connecting part 106 located at the feed end of the third sorting component is fixedly connected to the second connecting part 104 located at the discharge end of the second sorting component; the mesh diameter of the third screen 105 is larger than the mesh diameter of the second screen 103; a third hopper 109 is located below the third screen 105, with an opening at the top, and the opening area is larger than the orthogonal projection area of the third screen 105 at the top opening of the third hopper 109; a transmission component drives the first sorting component, the second sorting component, and the third sorting component to rotate coaxially.
[0033] When the material enters the sorting device, due to the tilting and rotation of the first, second, and third sorting components, the material tumbles and rolls on the screen surface of the first screen 101. Qualified adhesive powder (undersize product) below 40 mesh is discharged through the first hopper 107, while unqualified material (oversize product) is fed into the second screen 103 via the first connecting part 102 and the second connecting part 104 for further sorting. Unqualified material (oversize product) discharged from the first sorting component enters the second screen 103 for further sieving. Qualified film (undersize product) below 10mm is discharged through the second hopper 108, while unqualified material (oversize product) is fed into the third screen 105 via the second connecting part 104 and the third connecting part 106 for further sorting. Unqualified materials (oversize products) discharged from the second sorting section enter the third screen 105 for further screening. Qualified films smaller than 20mm (undersize products) are discharged through the third hopper 109, while unqualified materials (oversize products) are output from the third connecting section 106 to the sorting device for further processing. Simultaneously, if... Figure 3As shown, in order to quickly output the product on the screen to the sorting device, the inner surface of the third connecting part 106 is provided with a spiral lifting plate.
[0034] In some embodiments, the waste tire rubber breaking and sorting equipment also includes a dual-shaft counter-roller rubber grinder 2 connected to the sorting device via a first connecting part 102, and a rubber block buffer silo 3 connected to the feed port of the dual-shaft counter-roller rubber grinder 2.
[0035] Waste tires and waste rubber are cut into approximately 50mm x 80mm blocks using specialized cutting tools. These pyrolysis rubber blocks are then loaded into a rubber block buffer silo 3 using a loading tool. The inlet of the rubber block buffer silo 3 is located on the top of the silo. The rubber block buffer silo 3 is a separate unit, meaning it is separate from the lower support frame.
[0036] The rubber block buffer silo 3 has four lug-type supports at its four corners at the bottom. Four sets of vibration springs are installed under these supports, providing support and shock absorption. Vibration causes the material to move within the silo, thus achieving the goal of material downward movement. Two sets of high-frequency vibration motors are installed on both the front and back of the silo body. These motors generate vibration force, which is transmitted to the silo body to prevent material bridging. The lower part of the rubber block buffer silo 3 has support frames corresponding to the four lug-type supports.
[0037] The rubber block buffer silo 3 has a discharge port at its lower part, which connects to the feed port of the buffer hopper at the upper part of the twin-shaft counter-rotating rubber mill 2. The twin-shaft counter-rotating rubber mill 2 functions by using two shafts rotating in opposite directions to clamp the rubber block between the two rotating shafts. Under the action of axial force and extrusion force, the rubber block is broken into irregular flakes and powdery particles, which are then fed into the discharge chute through the discharge port at the lower part. The material output from the discharge chute enters the kiln head (first connection part 102) at the feed end, such as... Figure 4 As shown, a spiral lifting plate is installed inside the feed end cylinder, which can move the incoming material in a spiral manner and send it into the first screen 101.
[0038] In some embodiments, the sorting device is connected to the inlet of the rubber block buffer silo 3 via a second connecting part 104 or a third connecting part 106. The waste tire crushing and sorting equipment also includes a bucket elevator 4, through which the sorting device is connected to the rubber block buffer silo 3. With this arrangement, waste tire particles that are too large and do not meet the requirements discharged from the sorting device are discharged into the inlet of the bucket elevator 4, lifted by the bucket elevator 4 to the discharge port, unloaded into the inlet of the rubber block conveyor belt 5, and then discharged into the rubber block buffer silo 3 via the discharge port of the rubber block conveyor belt 5, where they are further crushed by the twin-shaft counter-roller rubber crusher 2.
[0039] The working process of the above-mentioned waste tire debriding and sorting equipment is as follows:
[0040] Waste tire particles of different sizes entering the sorting device are conveyed to the first screen 101 through the first connecting part 102 for screening. The oversize material after screening is conveyed to the second screen 103 through the first connecting part 102 and the second connecting part 104 for screening, thereby achieving the grading of waste tire particles of different sizes.
[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
